On the convergence of inexact Newton method. (Chinese. English summary) Zbl 1040.65045
Summary: Local convergence of the inexact Newton method is discussed. Under the supposition that the semi-continuous second Fréchet derivative $$f''(t)$$ satisfies a modified first order-$$\gamma$$ condition, its second order convergence is studied and error estimates are obtained. Instead of a stronger condition, a weaker condition is used here. Error estimates of the radius of convergence are given.
